To alwhommayc'ofncem:

Berit known that I, C' S. PARKER,

a citizen of the United States, residin at Boston, in the county of Suffolk and tate n of Massachusetts, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.

This invention relates to improvements in safety razors. Since the advent of the first razor of this type many e'orts have been made to. improve them, but every type now available, so far as I am aware, is open to objections in the way of multiplicity of parts and expense formachine work in its production. the elimination of which is among the objects of the present invention. And although razors now known are transformable into a lmocked-down condition, they are still so bulky as to require carriage in a traveling bag and cannot be put into a sullicientl small space to satisfy the ideal of one w ose taste or necessity makes him fastidious in that respect.

It is an object of the invention to meet these means without sacrifice of normal size,

rigidity of blade, or of eiliciency of shaving' qualities. n the complete razor of the invention by which these objects are attained, the holder for the blade has only two parts, one of which provides the guard for the cutting edge, and positions the blade with regard to it, and the other of which coacts therewith to retain the blade rigidly, and serves as the handle. The separate parts may be stamped'from sheet metal in one operation, and bent to shape in the second operation; so that, aside from finishing l' or plating, no other work is required in their production. The blade may be of any of a number of standard makes and sizes now on the market, or may be specially desigped, with sin le edge or double edge. The w ole, when taen apart, maybev packed with the handle, blade and platev in parallelism, substantially within a space required for the lplate and its guard edge alone; so small as to, mean only -an unappreciable shape and weight in ones waistcoat pocket, or on ones ke ring. l

t is mtended that the patent shall cover,

b suitable expression in the ap nded c aims, whatever features ofpatentablii5 novelty exist in the invention disclosed n the drawings: f AFigure 1 is a ront elevation of one embodiment of the invention;

Figure2 is a side jperspective partly in section, on line 2-2 o Figure 1;

' Figure 3 is a front elevation of a modcation, showing a dilferent style of handle;

Figure 4 is a side elevation of the modiiication seen in Figure 3, with ortions shown in section on the line 4-40 Figure 3;

Fi re 5 is a front elevation showing still anot er application of the invention, this being Yin connection with a blade having two cutting edges; v

Figure 6 is a side view of the structure of Figure 5, partly in section on the line 6 6 .of Figure 5; and

Figure 7 is a plan of'the structure of Figure 5, in section on the line 7-7 of Figure 5.

Referring to the ldrawin s, an oblong holder and guard plate 10 1s provided by stamping from thin sheet metal of suitable quality and thickness, and by the stamping is provided with an elongated opening 12 along that which is to beits guard edge.

In Figure 1 the upper corners are shown clipped, but this is a matter of taste, and the corresponding parts in Figures 3 and 5, are unclipped and in Figure 5 constitute a guard for the second edge of a two-edged blade. l

The lower ed e of the holder plate is turned backwar from the eye, as seen in Figure 1, to form a guard lian e 24 by being bent on lines 13 at the end o? the opening, and the part of said Harige which constitutes the ed e of the opening l2 is serrated with guard ngers 16 projectin into the opening. The o posite side 18 o the opening 12 is a straig Vt edge and, in the finished razor, may be beveled on its front as at 19 to rmit the blade to operate close to the sur ace that is to be shaved. The parts 20 of the plate 10 at'the ends of the opening 12 support the ilange 24 and are guards which protect the sh'avers face from 'the corners of the razor 28, which lie back of it as seen .by dotted lines in Figure 1. At the top edge of the plate 10 is a small flange 22, also bent backward. Lugs 26 may also be turned back in the positions shown in Figure 1 where they engage the side edges of the blade 28 to limit its slipping down and sidewise on the holder.

The holder constituted by the plate l0 and its turned back'lugs 26 and flange 22 makes a sort of cup into which the blade 28 may be laid whenpthis is held with the flange 22 and lugs i 26 projecting upwards. .In that case Athe flange 22`and ugs 26 position the blade in such location that its cutting' edge 29 runs along the opening 12 and is exposed through it. It is clam ed 1n that po.- sition by the handle 32 whic in the shape illustrated in Figures 1 and 2 is made of a piece of spring bar metallone end of which is bent at 38 into a h ook or loop whose end 34 and part 36 next back -of` the bend 38 constitute the two spring clamping members which embrace the blade 28 and the holder plate 10, pressing them flat together. It 1s applied by sliding it downward, as the parts are represented in Figures 1 and 2, from the top edge into the position illustrated. To

hold the parts firmly together while the razor is in use, the notch is shaped in the outer edge of the guard flange 24, just wide enough to receive the barof the handle 32, and the handle itself is bent at such an angle from the clamping hook- 34, 36, that when the bend 38 of the latter becomes seated in a notch 14 in the flange 22, against the top edge of the plate 10, the shank of the handle 32 becomes seated in the notch 40. So long as the handle bar remains thus seated in the ler:

notches 14. 40, it cannot be slipped or twisted sidewise, and the wholeis secure. `Friction tends to hold everything in place because of the clamping; and there is no tendency for the clamp to be displaced upward because when in use the handle is pulled only downward; and in so far as the parts are subject to any upward pressure of the users.beard or face on the guard 24 or on the cutting edge 29 of the blade, that upward pressure merely tends to seat the two the 'more firmly within the loop, and to seat the back ed of the blade 28 the more firmly against t e top flange ofthe holder plate. In thisl po'-l sition the razor is ready for use. The remainder of the handle 32 may be made in any suitable shape, one shape beingillustrated in Figure 2. When thus shaped .it is conveniently and firmly held by the user between his thumb placed onthe side which toward the eye in Figure 2, his second finger on the side which is away from 'the eye, and

his first finger in the hollow 33, or bridging across that hollow from the point 35. Totake the instrument apart lone holds the blade 28 and plate 10 between thumb and :torefinger of onehand, and pushes'upwar'd on the handle with the other hand causiii? the

clamping loop

34, 36, 38, to slip oifan so leaving lthe blade 28 free to be lifted or l oblong hole l14 into` which' rojects the end Y 46 of a handle 32made o flat bar metal. The end which thus penetrates the hole 14 constitutes the fulcrum of a lever which has a bend of about 45 at 47, where it is ap-V plied to the flat side of the blade and presses the blade 28 against the plate 10. Further swinging of the lever in the same direction gets it to position where it is latched by engagement with the guard flange24. The

latter has a sub-flange 50 in which is a recess 49, in which recess is a tongue 48 that constitutes the latch by springing into an opening 31 in the flat bar handle 32. This latch is constituted by the spring action of the guard flange 24 and adjacent parts 20 of the holder plate 10, which permits the,

part V24 to be pressed` downwardto the left as [seen in Figure. 4 farV enough for the -tongue 48 to slip into and out of the hole 31A in the handle. For assembling, the parts need only to be put together andpressed together. For taking apart one presses in the proper direction on the flange 24 in order to draw the tongue 48 out of the handle.

Figures 5, 6 and 7 illustrate another modi fication. In this case the blade 28 has two cutting edges 29 the one which is not set forl use being fully protected by lying against the plate 10 as in the case of plate 10 shown in the other figures, except that the positionving lugs 26 and blade notches 30 are set'sothat its upper edge 29 does not touch the upper flangeI 22 of the plate 10'. Said upper flange 22 extends for the full length of the plate 10" thus projecting the entire length of the edge of the blade. The pl'ate 10 v might be designed for the blade 28 thusy positioned on the plate 10 to be clamped thereon'bya spring clamp handle l as shown i'n Figures 1 and 2; but a still different method is illustrated in Figures 5,- 6

and 7 wherein the plate 10 .is represented as `having a formation .42 of metal stamped in its midst, constituting a face groove, which v is clearly seen" in Figurel 7 partg34 of the' handle can in'it is held by the walls of the groove'so that it cannotl twister slip sidewisef? f.

Other variatlons may be made in into which A the slide, andl wherestructingthe razor-.fief the invention.

,afeature that the ty'pe of construction depress together the plate and blade.

plate with ard dan v gu bidi and a bent dat bar handle adapted to en parts re uired are the handle and the. -f' ing hol er. These latter may beso smallV as to be substantially no. greater in le" -h and breadth over all than the blade itse f; and ample strength is obtained iffv the bar metal emplo ed is only a quarter of an inch broad. As t e guard 24 need not be so wide as this, it makes the whole, when the handle is removed and laid fiat on the bladeand plate 10, occupy a s ace under five-sixt,- teenths of an inch thic and barely lar er than the blade. When placed in a suite 'le case these parts are an unappreciable burden to one who has occasion to carry them. The manufacture, at the same time, is so simple f "f that the whole may be inexpensive.
